The Gadgeteer evaluated emergency entry solutions across four smart deadbolts when primary batteries fail. The analysis highlights that Ring's announced lock plans an integrated manual charging dial, Yale's Matter deadbolt relies on a traditional physical key, Schlage's Sense Pro requires an exterior USB-C jumpstart, and Aqara's U400 offers both a keyway and emergency USB-C power. The author concludes that ecosystem requirements and backup access preferences should dictate choice, though Ring's crank mechanism remains unreleased and untested.

## Buying guide

The article compares four smart locks by their documented dead-battery backups and access features, but does not test reliability hands-on. It frames the choice around whether buyers prefer a key, emergency power, or Ring's announced on-lock dial.
